Key Traits of Emerging Smart Cities – Part 2: Energy, Transport, IoT, and Sustainable Urban Solutions

IoT analytics show that smart‑city initiatives now represent roughly 20% of global IoT projects. In Part 1 of this series we introduced several foundational traits; today we’ll delve deeper into the next wave of innovation.

A conventional power grid delivers electricity one‑way from utilities to consumers. A smart grid reverses that paradigm, enabling two‑way communication that allows utilities and customers to negotiate supply and demand in real time.

Smart city traits:

• Smart Energy

A smart grid integrates advanced communication, control systems, and emerging technologies to make the network more efficient, reliable, secure, and environmentally friendly. According to HQSoftware’s CEO, this platform supports renewable sources such as wind and solar, while dynamically balancing supply and demand.

Traditional grids are vulnerable to cascading failures that can disrupt communications, traffic, banking, and more. The two‑way nature of a smart grid enables automatic rerouting during outages, mitigating such domino effects.

Key challenges include managing peak consumption—when thousands of households simultaneously draw power—and the limited storage capacity of conventional networks. Smart grids solve this by incorporating distributed generation: rooftop solar panels, EV batteries, and other micro‑generators can feed excess energy back into the grid and draw from it when needed.

Barcelona’s 2012 Smart City World Expo project exemplifies this approach. Its street lamps now adjust brightness based on pedestrian presence, incorporate Wi‑Fi, and monitor air quality. The initiative cut lighting energy use by 30%, saving approximately $37 million (€31.24 million) annually.

HQSoftware recently replicated a similar system for a German manufacturing client. By equipping each bulb with Wi‑Fi, the factory’s lighting turns on automatically when a worker’s smartphone enters the zone.

Smart Transport

Europe is accelerating the rollout of electric refueling infrastructure, with Norway leading the way: 37% of new car sales were electric in 2017, and the country aims for 100% by 2025. China is projected to surpass Norway as the largest EV market by 2020.

Electric buses are also gaining traction across European cities. Toyota’s Intelligent Transport Systems Proving Ground at the Hitachi‑Fuji centre showcases a comprehensive smart‑transport ecosystem that connects vehicles, roads, and pedestrians to reduce accidents and enhance comfort.

Barcelona’s digital bus stations provide route information, USB sockets, free Wi‑Fi, and QR codes that link to a city‑wide app, reinforcing the city’s reputation as an IoT leader.

Beyond vehicles, smart parking systems use sensors to report real‑time availability to drivers’ mobile apps, cutting congestion, saving time, and increasing revenue for parking operators.

Internet of Things in Healthcare

IoT can revolutionize healthcare by automating workflows and eliminating paperwork. HQSoftware recently developed a fully digital interface for a dental chair equipped with a minicomputer and touchscreen. The solution, accessible via web on PCs, smartphones, tablets, and laptops, allows practitioners to adjust speed, lighting, and sound, and to share control through QR codes or direct requests.

Smart Territory Improvement

Barcelona uses IoT for irrigation and fountain water‑level monitoring. Sensors track humidity and precipitation, ensuring water is applied only during drought conditions. This system saves the city approximately €468.53 k per year.

By aggregating real‑time data, municipalities can allocate budgets more efficiently, avoiding both overspending and under‑funding. Smart‑city technologies thus enable a more responsive and sustainable model of urban life.
